Description

Technical Field

[0001] The invention relates to a tripod type loudspeaker. Background Art

[0002] At present, single speakers and tripods are used in more and more occasions, such as police cars, ambulances and other vehicles that handle emergency incidents. However, these speakers and tripods are usually independent, with low integration, large duty cycle, and low information integration of long rows of warning lights. Summary of the invention

[0003] In view of the shortcomings of the prior art, an object of the present invention is to provide a tripod-type loudspeaker.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A tripod type loudspeaker, comprising a tripod shell, a tripod cover and a sound generating assembly, wherein one end surface of the tripod shell facing the tripod cover is provided with two symmetrically arranged three-stage amplification channels, and the other end surface is provided with a sound generating chamber for placing the sound generating assembly;

[0006] One end of each three-stage amplified sound channel is provided with two sound outlets connected to the sound-emitting chamber, and the other end is bent and extended outward to the corresponding side wall of the tripod shell, and is provided with a sound-emitting tube.

[0007] The present invention further provides: the sound-generating component includes a voice coil and a drum basin sound membrane, wherein the voice coil includes an annular frame, the drum basin sound membrane is inverted in the middle position of the annular frame, and the annular frame is provided with a plurality of evenly distributed magnetic steel grooves for placing the magnetic steel.

[0008] The present invention further provides that: the tripod shell and the tripod cover are cast by aluminum.

[0009] The invention has the beneficial effects that the two three-stage amplification channels arranged on the tripod housing are independently closed to form a single sound source, so that the tripod-type speaker can emit sound in both directions, and after the police car is installed, both the front and rear sides can be warned in a balanced manner;

[0010] The three-stage amplification channel and the sound chamber are respectively arranged on the upper and lower end surfaces of the tripod shell, which effectively reduces the overall height of the tripod speaker and makes the tripod speaker more compact; each of the three-stage amplification channel is connected to the sound chamber through two sound outlets, and the double sound outlets are combined to make the sound stronger and more powerful, and the other end is bent and extended outward to the corresponding side wall of the tripod shell, and a large sound outlet tube is provided, so that the sound can be amplified in three levels and the sound can be made stronger and more powerful.

DETAILED DESCRIPTION

[0018] Refer to the attached Figures 1 to 6 A tripod-type loudspeaker embodiment of the present invention is further described in detail.

[0019] from Figure 1 and Figure 2 It can be seen that a tripod type speaker includes a tripod shell 1, a tripod cover 2 and a sound-generating component 3. The tripod shell 1 and the tripod cover 2 are cast by aluminum material, wherein the die-cast aluminum material has the characteristics of strong rigidity, good heat dissipation and long life, which is convenient for heat dissipation and effectively avoids the tripod type speaker from being deformed by force, thereby effectively ensuring normal sound.

[0020] from Figure 3 It can be seen that the tripod shell 1 is provided with two symmetrically arranged three-stage amplifying sound channels 11 on one end surface facing the tripod cover 2, and the other end surface is provided with a sound chamber 12 for placing the sound-generating component 3, so that the two three-stage amplifying sound channels 11 arranged on the tripod shell 1 are independently closed to form a single sound source, so that the tripod-type speaker can make sounds in both directions, and the police car can be evenly warned from the front and rear after installation. The three-stage amplifying sound channel 11 and the sound chamber 12 are respectively arranged on the upper and lower end surfaces of the tripod shell 1, which effectively reduces the overall height of the tripod-type speaker, making the tripod-type speaker more compact.

[0021] from Figure 4 and Figure 5It can be seen that two sound outlets 13 connected to the sound chamber 12 are arranged at one end of each three-stage amplification channel 11, so that each three-stage amplification channel 11 is connected to the sound chamber 12 through the two sound outlets 13. The two sound outlets 13 converge to make the sound stronger and more powerful. The other end is bent and extended outward to the corresponding side wall of the tripod shell 1, and a sound outlet tube 14 is arranged, so that the sound can be amplified in three levels and the sound can be made stronger and more powerful.

[0022] from Figure 6 It can be seen that the sound-generating component 3 includes a voice coil 31 and a drum basin diaphragm 32, wherein the voice coil 31 includes an annular frame 311, and the drum basin diaphragm 32 is inverted in the middle position of the annular frame 311, which effectively saves the installation space of the diaphragm and makes the overall structure of the speaker thinner. In addition, the annular frame 311 is provided with a plurality of evenly distributed magnetic steel grooves 312 for placing the magnetic steel 4, and the material of the magnetic steel 4 is neodymium iron boron, which has high magnetic flux and low cost. The cylindrical magnetic steel 4 is arranged on the annular frame 311 instead of the annular magnetic steel 4, which effectively reduces the amount of the magnetic steel 4 and reduces the cost.

[0023] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
